FASTENING-INSEB-TING MACHINE.

T0 aZZ whom it may concern:

.Be it known that I, EDWARD ERIoKsoN, a citizen of the United States,residing at Beverly, in the county of Essex and State of lliassachusetts, have invented certain Improvements in Fastening-Inserting Mach nes, of which the following description, nconnection with the accompanying drawlngs, 1s a specification, likereference characters on the drawings indicating like parts i in theseveral figures.

This invention relates to machines for inserting fastenings in shoes,and more particularly to machines constructed and arranged to insert aplurality of fastenings at one operation into shoe parts to secure thesame in place.

An object of the invention is to provide a satisfactory duplex or pluralfastening in serting mechanism which will be adapted to drive thefastenings in very close juxtaposition, while at the same time beingcapable of a substantial range of variation in fastening positions, andwhich will be simple and economical as well as convenient and rapid inoperation. The invention is herein shown for the purpose ofillustration, but not by way of limitation, as embodied in a machinedesigned with especial reference to use for inserting fastenings tosecure shank stiifeners to the soles of shoes.

Important features of the invention consist in a novel and improvedorganization whereby provision is made for the desired adjustments ofthe fastening inserting mechanisms. In the illustrated embodiment of theinvention these mechanisms are constructed and arranged for simultaneousand uniform adjustment toward or from each other. means being providedto secure them in any adjusted position. As shown, the fasteninginserting mechanisms are pivotally mounted to move inwardly over thesoles of shoes and have associated with them controlling means arrangedto swing the fastening inserting mechanisms about their axes foreffecting uniformly equal and opposite adjustments of said mechanismsabout their axes of pivotal mounting.

These and other features of the invention, including numerous details ofconstruction and combinations of parts, will be more fully explainedinthe following description and then pointed out in the claims.

Specification of Letters Patent. Patented Aug. 15, 1922. i Applicationfiled March 23, 1918.

Serial No. 224,186.

Fig. 2 is a view in side elevation of the 7 same machine; and

Fig. 3 is a detail showing the presentation of the work to the fasteninginserting devices.

The illustrated. embodiment of the invention comprises a fasteningsupplying mechanism 4 of any well-known type, which separates twofastenings at a time; and delivers them simultaneously to deliveringtubes 6 which deposit the fastenings in the desired location in thefastening inserting mechanisms.

In performing the special work for which this machine is designed twoonly of the fastening inserting mechanisms 8 are provided, though itwill be understood that a larger number could well be arranged in pairsin the manner shown should it be found desirable to insert a largernumber of fastenings than is here considered necessary. Inasmuch as thefastening mechanisms are identical in construction and operation, adescription of one will apply equally well to the other. For thepurposes of illustration, each inserting mechanism is shown ascomprising a substantially tubular driver guidev l0 pivoted at 12 to theframe let of the machine. The guide members are pivoted at their upperends so that the lower ends may be adjusted toward and from each otherby any suitable means, a preferred form of which will now be described.Each guide member 10 is preferably provided with a projecting stud 16which extends into a cam slot 18 in a member 20 rotatably mounted at Itis obvious that upon depressing the handle 24: (in Fig. 1) on member 20,the fastening 1nserting devices will be-caused to separate or recedefrom one another. Upon turning the handle in the opposite direction, thesaid mechanisms will be adjusted toward each other to drive thefastenings in close juxtaposition. Mounted in each driver guide 10 is adriver bar 26 having at its lower end a driver 28; Each driver bar isconnected to the crosshead 30 preferably by means of a block 32 slidablein a T-shaped slot in the crosshead, there being a ball and socketconcrosshead being urged downwardly on its crosshead the usual linkconnection 48.

operative stroke by means ofthe spring-op erated lever 4:6, there beinginterposed. between said lever and the upper end of the In order tolessen the jar of the machine and to limit the downward movement of thecrosshead, a buffer 50 is providedconsisting pref erably of leatherdiskssurrounding the guid ing bar 36. It willbe observed that the fastening1nserting mechanisms are so arranged that each is inclined downwardlyand inwardly so that a fastening driven thereby has its point directlytoward the median line of the shoe as it is driven through the shankstiffener member in securing the same to the sole of the shoe. ristheshoe bottom is slightly convex at the part where tastenings are tobeinserted, the inclined inserti be turned to effect the adjustment ofthe iii-1s ibe of any preferably n j granted. to Nye and. Copeland, We464:,200,

ing mechanisms drive the fastenings in a direction substantially normalto the shoe bottom. In adjusting the fastening inserting deviceswithrespect to each other, the securing member is mani giuiated to releasethe cam member :20 which may then tening inserting mechanisms withrespect to each other, after which the securing member 52- isagainadjusted to hold the cam member fixedly in position. In the operation ofthe machine two fastenings are separated from the fastcnings in therace,

ways and delivered .simultaneously to the tubes 6 while the drivers arein raised position.

Each fastening inserting device is provided at its" loiver end with anozzle 54: to" hold and properly guide the fastening whileit is beingdriven. This nozzle may of the well-known types but is like thatdisclosed in the 'patent December 1, 1891'; When the drivers dje scendthev drive the fastenings from the nozzles nto each s de of the shankstiffener which hasbeenvproperly positioned uponthe shoe bottom asndicated in Fig. 3. The

a machine has been provided with one-revolutionclutch so that theworkman must def press, thetreadlc each time a shoe is presented to thefastening inserting mechanisms for the insertion of fasteners. iPreferably the and thebralce member and clutch are so arranged h t heshaft comes area the shoe twice in succession to a tacker of the oldtype to suit. y j v Havin described my invention, what I claim as newand desire to secure by Letters accomplish the same desired re- Patentof'the United States is i 1.
